Question

What is the equation of a vertical line passing through the point (-4, 7)?

O y = 7
O y = -4
O x = 7
O x = -4

Answer 1

x = -4

Explanation:

vertical line is parallel to y-axis so its equation is always x = x₀

at any given point we have coordinates: (x₀, y₀)

given point (-4, 7) means x₀ = -4

so the equation of a vertical line passing through the point (-4, 7) is x=-4
